[0001] This utility model relates to the field of nonwoven fabric production equipment technology, specifically to a device for preparing PHBV antibacterial nonwoven fabric. Background Technology

[0002] PHBV antibacterial nonwoven fabric is a type of nonwoven fabric made from polyhydroxybutyrate-valerate copolyester (PHBV) and possesses antibacterial properties. PHBV is a novel biopolymer, copolymerized from 3-hydroxybutyrate and 3-hydroxyvalerate, exhibiting excellent biodegradability. This material is produced using starch as a raw material through fermentation engineering technology and can completely decompose into carbon dioxide, water, and biomass under soil or composting conditions, hence its designation as a "green plastic." The preparation of this material often requires specialized equipment.

[0003] The existing technology has the following shortcomings: The prior art, CN116837546A, entitled "An apparatus for preparing PHBV antibacterial nonwoven fabric," "includes a base, a front baffle assembly, a cover assembly, a drive assembly, a guide assembly, a hydroentangling mechanism, and a back plate. The back plate and the front baffle assembly are vertically arranged on the front and back sides of the base, respectively. The cover assembly and the drive assembly are both arranged on the front baffle assembly. It also includes nonwoven fabric and multiple rollers of different sizes, the rollers being detachably snapped onto the cover assembly. The drive assembly is linked to the rollers."

[0004] The aforementioned structure, through the coordinated arrangement of a base, front baffle assembly, cover plate assembly, drive assembly, guide assembly, hydroentangling mechanism, and back plate, allows the invention to automatically disassemble the conveyor belt curtain. However, this structure cannot adjust the winding size during the production of antibacterial nonwoven fabrics, thus limiting its applicability and narrowing its scope of application. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a device for preparing PHBV antibacterial nonwoven fabric, which solves the problem that the current winding and wrapping steps cannot be adjusted in size as needed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for preparing PHBV antibacterial nonwoven fabric, comprising a main support, a control panel, a motor and a drive gear, wherein the control panel is disposed on the side of the main support, the motor is disposed on one side of the main support, and the drive gear is disposed at the front end of the motor;

[0007] A support shaft is provided on one side of the main support, an adjustment handle is provided on the outer periphery of one side of the support shaft, a support frame is provided on the outer side of the support shaft, and a shaft seat bracket is provided at the other end of the support shaft.

[0008] The support shaft also includes a driven gear, an adjusting thread, a fixed ring, and an adjusting ring. The driven gear is fixedly connected to the outer end of the support shaft. The adjusting thread is opened on the outer end face of the other side of the support shaft near the end. The fixed ring is sleeved on the outer end face of the support shaft. The adjusting ring is threadedly connected to the outer end face of the adjusting thread.

[0009] As a preferred embodiment of this utility model, the support frame further includes a connecting rod and a positioning shaft. The connecting rod is movably connected to the inner end face of the support frame, and the positioning shaft passes through the connecting rod and the support frame, thus keeping the connecting rod movably connected.

[0010] As a preferred embodiment of this utility model, the other end of the connecting rod is movably connected to the outer end face of the fixed ring and the adjusting ring via a positioning shaft.

[0011] As a preferred technical solution of this utility model, the fixing ring is provided in two sets, one set is provided on the outer end face of the support shaft in contact with the main body bracket, and the other set is provided on the outer periphery of one end near the shaft seat bracket.

[0012] As a preferred technical solution of this utility model, the connecting rod has two connection orientations: the connecting rod connected to the fixing ring is inclined towards the right side of the bearing bracket, while the connecting rod connected to the adjusting ring is inclined towards the main body bracket.

[0013] As a preferred technical solution of this utility model, the connecting rod is installed in a two-in-one manner, and the positioning shaft passes through two sets of parallel connecting rods at the same position.

[0014] As a preferred embodiment of this utility model, the support frame is provided in four sets, which are equidistantly distributed around the support shaft, and the four sets of support frames are arranged in a ring position distribution.

[0015] Compared with the prior art, this utility model provides a device for preparing PHBV antibacterial nonwoven fabric, which has the following beneficial effects:

[0016] This apparatus for preparing PHBV antibacterial nonwoven fabric comprises a support shaft, a support frame, a driven gear, a fixed ring, and an adjusting ring. During operation, the operator controls the motor via a control panel. First, the antibacterial nonwoven fabric material is wound around the support frame. Then, the motor drives the drive gear, which in turn drives the driven gear. The support shaft, connected to the driven gear, rotates under the support of the main support and the shaft seat, winding the outer antibacterial nonwoven fabric material. To control the winding diameter, the operator can rotate the adjusting handle to move the adjusting ring around the adjusting thread. To increase the winding diameter... The diameter can be adjusted by adjusting the ring towards the main support. When the adjusting ring moves towards one end of the main support, the connecting rod is lifted outward through the positioning axis, thereby lifting the outer support frame. After the four sets of support frames are lifted, the winding diameter is expanded. If it is necessary to reduce the winding diameter, the adjusting ring can be moved in the opposite direction, so that the connecting rod is closed through the positioning axis to the support shaft, thereby making the outer support frame close to the support shaft and reducing the winding diameter. Through the above settings and process, the equipment can not only quickly wind and prepare non-woven fabric materials during use, but also adjust the winding diameter, enabling the equipment to wind and prepare non-woven fabric materials of different required sizes, increasing the scope of application and improving the preparation efficiency of antibacterial non-woven fabrics.

[0023] Please see Figure 1-4 In this embodiment: a device for preparing PHBV antibacterial nonwoven fabric includes a main support 1, a control panel 2, a motor 3 and a drive gear 4. The control panel 2 is located at the side end of the main support 1, the motor 3 is located on one side of the main support 1, and the drive gear 4 is located at the front end of the motor 3.

[0024] A support shaft 5 is provided on one side of the main support 1, an adjustment handle 6 is provided on the outer periphery of one side of the support shaft 5, a support frame 7 is provided on the outer side of the support shaft 5, and a shaft seat bracket 8 is provided at the other end of the support shaft 5.

[0025] The support shaft 5 also includes a driven gear 501, an adjusting thread 502, a retaining ring 503, and an adjusting ring 504. The driven gear 501 is fixedly connected to the outer end of the support shaft 5. The adjusting thread 502 is opened on the outer end face of the other side of the support shaft 5 near the end. The retaining ring 503 is sleeved on the outer end face of the support shaft 5. The adjusting ring 504 is threadedly connected to the outer end face of the adjusting thread 502.

[0026] In this embodiment, the support frame 7 further includes a connecting rod 701 and a positioning shaft 702. The connecting rod 701 is movably connected to the inner end face of the support frame 7, and the positioning shaft 702 passes through the connecting rod 701 and the support frame 7, keeping the connecting rod 701 movably connected. The other end of the connecting rod 701 is movably connected to the outer end face of the fixing ring 503 and the adjusting ring 504 through the positioning shaft 702. The fixing ring 503 is provided in two sets, one set is provided on the outer end face of the support shaft 5 in contact with the main bracket 1, and the other set is provided on the outer periphery of one end close to the shaft seat bracket 8.

[0027] Specifically, by setting two sets of fixing rings 503, the support frame 7 can be supported on the outside, thereby maintaining the overall stability of the support frame 7;

[0028] In this embodiment, the connecting rod 701 has two connection orientations: the connecting rod 701 connected to the fixing ring 503 is inclined towards the right side of the bearing bracket 8, while the connecting rod 701 connected to the adjusting ring 504 is inclined towards the main body bracket 1; the connecting rod 701 is installed in a two-in-one manner, and the positioning shaft 702 passes through the two sets of parallel connecting rods 701 at the same position.

[0029] Specifically, by having a set of positioning shafts 702 pass through two sets of parallel connecting rods 701, the movable support structure can be made more stable, and the connecting rods 701 can remain stable and fixed when the support frame 7 moves.

[0030] In this embodiment, four sets of support frames 7 are provided and are equidistantly distributed around the support shaft 5, forming a ring-shaped distribution.

[0031] The working principle and usage process of this utility model are as follows: When using this equipment, the operator controls motor 3 via the control panel. First, the antibacterial nonwoven fabric material is wound around the support frame 7. Then, the motor 3 drives the drive gear 4, which in turn drives the driven gear 501. The support shaft 5, connected to the driven gear 501, is then driven. The support shaft 5 rotates under the support of the main support 1 and the shaft seat support 8, and winds up the outer antibacterial nonwoven fabric material. If it is necessary to control the winding diameter of the antibacterial nonwoven fabric, the operator can adjust it by rotating the adjustment handle 6. The adjusting ring 504 rotates around the adjusting thread 502. If it is necessary to increase the winding diameter, the adjusting ring 504 can be adjusted towards the main support 1. When the adjusting ring 504 moves towards one end of the main support 1, the connecting rod 701 pushes outward through the positioning shaft 702, thereby lifting the outer support frame 7. After the four sets of support frames 7 are lifted, the winding diameter is increased. If it is necessary to decrease the winding diameter, the adjusting ring 504 can be moved in the opposite direction, so that the connecting rod 701 closes to the support shaft 5 through the positioning shaft 702, thereby making the outer support frame 7 close to the support shaft 5 and reducing the winding diameter.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
